How to Make Sea Salt
Commercial salt makers produce sea salt in much larger scale than a home salt maker would, but knowing the commercial techniques can increase your knowledge and salt making possibilities. Here's how they do it:
• Small ponds are filled with sea water and the water is left to evaporate. The product left behind after all the water is gone is sea salt. This process works best in areas where there is a lot of sun and very little rain.
• Salt water is piped into large steel pans. Any mud or impurities settle to the bottom and the remaining good water is siphoned off and heated. As the water heats, any foam that forms is skimmed off the top and the water continues to evaporate until only salt crystals remain.
• Additives are sometimes included. Commercial seas salt makers sometimes add calcium and magnesium to their salts to provide added nutrition and a distinct taste.
